Description

Authors should be able to create transparent windows by writing an alpha value of less than one.

This is easy to enable in winit, but when I tried to get this working but ran into weird issues with junk being left in the buffer. Will probably take some debugging to get right.

We'll need to make sure we're doing the right thing with respect to premultiplied alpha.

Contributor guide

Research direction
Investigate how to set transparency in winit, handling alpha channel correctly with premultiplied alpha, and debug any buffer artifacts.
